对建模与仿真技术学科的粗浅理解--为庆祝《计算机仿真》杂志创刊20周年而写

半个世纪以来，我国建模与仿真技术，无论在广度，还是在深度上都得到了飞速发展，而且勇攀世界科技高峰。可是，建模与仿真技术也是一门学科的问题，在我国尚未形成共识。该文给出了建模与仿真定义、仿真的分类，给出了仿真的校核、验证和确认的定义。描述了建模与仿真学科的涵盖以及仿真的结构，并对建模与仿真学科的特点进行了分析和介绍。

Comprehension on the Subject of Modeling and Simulation

Since half a century, the Chinese modeling & simulation developed at full speed no matter who is scope or depth, and olse it is scaling bravely world's heights in science and technology. However, the problem still remains to be solved in China that modeling & simulation are also a subject. This paper affords the definition of modeling and simulation (M&S), and describes the classification of simulation. The definition of verification, validation and accreditation is presented. The inclusion of the subject of M&S and the structure of simulation are described. The characteristics of the subject of M&S is also analyzed and introduced.
